An arc fault is a high power discharge of electricity between two or more conductors. An arc-fault occurs when loose or corroded connections make intermittent contact and causes sparking or arcing between the connections. This translates into heat, which will break down the insulation of the wire and can be the trigger for an electrical fire.
